Asthenopia (eye fatigue)

Pathography
Asthenopia — quickly coming eyestrain during visual work, especially at a small distance from the eye to the subject. Asthenopia — not a disease but a border state. However, if you do not pay attention, it can progress to a more serious zabolevaniya.Imenno time so it is important to address the problem and fix it.
Causes
Using your computer, regardless of the type of monitor.
Prolonged driving, especially at dusk and at night.
The work requires constant visual attention.
Prolonged reading.
Daily television viewing.
Incorrect glasses.
Wrong to illuminate in the living room and in the workplace.
Varieties
Accommodative asthenopia is the most common form of eye fatigue. It can be due to presbyopia, weakened as a result of accommodation of common diseases, spasm of accommodation. Since accommodation is more far-sighted people, especially during visual work at close range, the far-sighted people of accommodative asthenopia more common.
Muscular asthenopia can be caused by overexertion convergence. Unpleasant effects disappear if you close one eye, that is, off convergence. Exotropia may occur.
Mixed asthenopia, usually characterized combined picture and the accommodative muscle of eye fatigue. The reasons for its the same as that of each of them. Treatment combination.
Neurogenic asthenopia often seen as a manifestation of the general neurasthenia and hysteria. Therefore, it can occur when the part of the vision there are no prerequisites for the emergence of asthenopia.
Symptomatic asthenopia seen as a symptom that accompanies some inflammatory diseases of the eye and nose. Its connection with the visual work at a short distance is less obvious.
The main symptoms of
Asthenopia seen so-called «visual» and «eye» symptoms. In these cases, you may experience:
blurred vision,
ghosting and blurring of the image,
distortion of the shape and size of the observed objects,
inflammation of the eyes,
lacrimation,
eye fatigue, increase in temperature,
vglazah feeling of discomfort, pain, or burning rubber.
At the same time is often a headache, and irritability. Against this background, often develop complications such as conjunctivitis or blepharitis (inflammation of the eyelids).
Treatment
Possible early use corrective glasses for hyperopia, presbyopia and astigmatism. Children need to wear glasses all the time, adults (with presbyopia and hyperopia, weak or moderate) — usually only when reading or writing.
Prophylaxis
Every hour of hard work your eyes 10-15 minutes of rest. The best — look out the window: enjoy the scenery, looking from far to near objects, or simply the sky.
Adjust the position and illumination of the monitor, as well as indoor working places and premises. Avoid sudden changes in light — for example, working in a dark room for the brightly lit monitor.
Work in a comfortable position. For good vision and preventing asthenopia important good blood supply. Therefore, looking away from the monitor, do exercise or massage the neck area.
Use colloidal fitoformuly ED medicine, which contains all the necessary ingredients to strengthen the eyes, protect the retina and support optimal vision.

amblyopia of obscure

Amblyopia of obscure — lowering the severity of central vision due to corneal clouding the lens.
Causes
Play the role of functional inactive eye and related developmental delay visual analyzer.
symptoms
Characterized by low visual acuity, despite the removal of turbidity and the absence of pronounced anatomical changes in the retina.
diagnostics
Diagnosis is based on exclusion of other causes of low visual acuity.
treatment
Keratoplasty surgery or cataract surgery at an early age.
To improve vision — irritation of the retina light exercises to train the amblyopic eye.
A significant improvement in vision can not be trusted because its reduction is due not only functional, but also anatomical reasons.

hysterical amblyopia

Hysterical amblyopia — inhibition of visual perception in the cerebral cortex.
Causes
Occurs in hysteria, often accompanied by other functional disorders of the visual analyzer (violation of color vision, narrowing of the field of vision, photophobia n, etc.).
symptoms
A sudden decrease in visual acuity, usually bilateral, may be followed by a concentric contraction of the visual field, the appearance of the cattle, hemianopsia. Vision remains depressed for a few hours to many months. It is not easy to distinguish from the simulation.
diagnostics
Examination to detect asymmetry refractive disorders of the abductor and adductor muscles of the eyeballs (amblyopia in squint), the definition of true visual acuity of each eye separately.
treatment
Treatment is carried out with the help of psychotherapy and sedatives.

amblyopia DISBINOKULYARNAYA

 

Amblyopia disbinokulyarnaya — disorder of binocular vision in a friendly squint.
Causes
Continuous brake functions of central vision squinting eyes.
symptoms
Decrease the severity of central vision, usually large, frequent violation fixation. Points of view do not improve. These disorders are gradually becoming more stable, in some cases, irreversible.
Objectively, any change of refractive media and the bottom of the eye there.
diagnostics
Diagnosis is based on exclusion of other causes of low visual acuity.
treatment
Exercises to train the eye bliopicheskogo am (embroidery, painting, playing in a mosaic, etc.). In the absence of success, as well as a non-central fixation in children 6 years and over — complex treatment in special rooms.
With central fixation prompt treatment usually leads to an increase in visual acuity. When a non-central fixation is not always possible. Prevention. Early shutdown of the act of leading the eye when monolateral squint.
